Product Introduction
The GE 369-HI-0-M-0-E-0 is a Multilin 369-series motor management relay for protection, control, and diagnostics of three-phase AC motors. It monitors current, ground fault, and motor status, then uses programmable relay outputs to trip breakers, contactors, or alarms.
This build adds wide-range HI control power and metering, plus Ethernet and RS485 communications for SCADA or PLC integration. It supports thermal overload modeling, jam/stall protection, phase loss/unbalance, and event logging—useful for root-cause analysis without extra instruments.

Quality Control Process (DYNAMIC GENERATION)
- Nameplate and revision check: Verify 369-HI-0-M-0-E-0 ordering code, control power range, and communication options before wiring.
- Control power test: Apply rated HI supply and confirm stable boot, front-panel display, and LED indication.
- CT and ground-fault verification: Inject secondary current into phase and ground CT inputs, then check trip/alarm responses with a relay test set.
- Output relay validation: Energize Trip, Aux 1, Aux 2, and Alarm relays; measure contact continuity and verify fail-safe/non-fail-safe behavior.
- Communication check: Test RS485 Modbus RTU register reads and Ethernet connectivity, then confirm event logs and metering values. Pack in anti-static shielding with terminal protection.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm the exact ordering code. The “0” in the RTD position means no RTD module; swapping it with an “R” version will change terminal assignments and settings.
❗ Match CT ratios and wiring. Wrong CT ratio or reversed polarity causes false overload, unbalance, or ground-fault trips.
❗ Verify control power range before energizing. HI supplies accept wide voltage, but applying DC to an AC-only source—or vice versa—can damage the relay.
❗ Check Ethernet vs. RS485 addressing. IP conflicts, baud rate mismatches, or duplicate Modbus IDs will block SCADA communication even if the relay itself is healthy.
Keep these in mind and you’ll cut 90% of rework time.
